中国の輸出に内在する排出を1990〜2024年まで再構築。SO2、NOx、PM2.5はピーク比58〜89%減、CO2は高止まり。太陽光・電池・EV輸出のライフサイクル回避排出は製造排出の20〜43倍に達し、輸出部門の環境機能が逆転したことを示す。
English
Reconstructing emissions embodied in China's exports from 1990 to 2024, this study finds asymmetric decoupling: SO2, NOx, and PM2.5 fell 58-89% from peaks while CO2 remains near maximum. Exports of PV, batteries, and EVs now avoid 20-43 times their manufacturing emissions, indicating a functional reversal of China's export sector.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の輸出構造変化は、日本企業のサプライチェーン排出量（Scope 3）やCBAM等の国境炭素調整への対応に示唆を与える。中国製グリーン製品の輸入拡大は日本の排出削減に寄与する一方、地政学リスクも考慮が必要。
In the global GX context
This study provides empirical evidence on China's transition from pollution haven to decarbonization supplier, with direct implications for carbon border policies (CBAM) and global supply chain decarbonization. It highlights the growing role of Chinese clean-tech exports in global emissions reduction.

📄 Abstract（原文）
For two decades, China's export-driven growth made it the world's paradigmatic pollution haven: a substantialshare of itsairpollution and carbon emissions was embodied in goods consumed abroad. Yet nearly all evidence for this narrative predates 2017, missing China's clean-air actions and the rise of its clean-technology exports. Here we reconstruct emissions embodied in China's exports from 1990 to 2024 using the GLORIA multiregional supply-and-use tables together with the MEIC emission inventory. We find an asymmetric decoupling: embodied SO , NOx and primary PM2.5 have fallen by 58–89% 2 from their peaks, while embodied COremains near its maximum. Decomposition shows 2 thepollutiondeclinewasachievedinsituthroughintensityreductions,notthrough relocation of foreign demand. Meanwhile, exports of photovoltaics, batteries and electric vehiclesnowavoid,overtheirlifetimes,20–43timestheCOemittedintheir 2 manufacture (10–22 at half displacement, 12–36 with decarbonising grids). In 2024, the operatingstockoftheseproductsavoidedCOequalto27%ofexport-embodied 2 emissions (forecast-based); a functional reversal, not yet a net one. China's export sector hasnotmerelycleanedup;itsenvironmentalfunctionhasreversed,withdirect implications for carbon-border policy and for development pathways elsewhere.
